抄録

We propose the use of porous substrates and thin films of oxygen permeable ceramics as a method for separating oxygen from air. The porosity and pore size of various Ce_0.8Gd_0.2O_1.9; (CGO) porous substrates were modified in an attempt to optimize the oxygen permeable flux of CGO-CoFe₂O₄ thin films. The oxygen permeable flux density of the CGO-CoFe₂O₄ thin film coated on the porous CGO substrate was found to be 4.7 μmol cm^-2 s^-1 under a O₂ partial pressure difference (-log(P_OII/P_OI)) of 4.5 at 1000°C. This value is about 20 times higher than that of the 1 mm thick bulk material.
